LOUVRE-IBLIND SLA'I AND CLIP.

To all wkmit it may concern:.

Be it known that we, PERCY H. Wilson v and CHARLES H. SAPPER, citizens of the United States, and residing at Norfolk, county of Norfolk, State of Virginia, have invented certain new and useful Improve ments in Louvre-Blind Slats and Clips, of

which the following is a specification.

This invention relates to louvre blinds and more particularly to devices for carryin the slats of the blind.

he objects of the invention are to provide a device for carrying the slats of a louvre blind and supporting them on the blind collapsin means, without in any way cutting or per orating the slats, and which requires no fastenings, such as screws or nails, to secure the device to the slat; to provide an imperforate slatin combination with a clip which is detachably secured to the slat; to provide a blip which is secured to a slat by clampin the opposite edges thereof; to provide a c ip which does not require that the slats be of an exact width; to. provide a clip which may be manufactured-at a low cost; and. generally to provide a simple, efiicient, and light device' of the type mentioned. Other objects and features of novelty will be apparent from the description taken in connection with the drawings in which:

Figure 1 is an'inside elevationof a frame having a louvre. blind of the type with which we prefer to use the devices constituting the subject matter of this applica tion;

Fig. 2'is a transverse sectional view of the.

top portion of the blind and frame and illustrating one manner of supporting the slat carrying clips; f i Fig. 3 is a perspective view of one form of clip;

Fig. 4 is a in two clips clamped thereon; r

%ig. 5 is a perspective view of one end of a clip showinga modified form of eye at the end of the clip;

Fig. 6 is a perspective View of another form of clip.

In order to fully disclose the manner of using and assembling the devices of the present invention ina louvre blind, it has been illustrated in connection with a blind of the type described and claimed in' our Specification of Letters Patent.

Referring tothe drawings it will be seen the blind is shown in the usual frame 10 of a window, although it is to be understood that the use of the blind is not limited to windows, but may be employed in other locations and for other purposes. As shown, a top support 11 is provided and this support has the spaced depending angle brackets 12 in which the shaft 13 is rotatively mounted. The-ends of the shaft project outside said brackets 12 and carry the sprocket wheels 13 which are arranged withln the partial housings 14 and have toothed segment 18 is secured to the slat and meshes with a worm 19 rotatively sup-. ported in the brackets 20 fastened to the support 11. The axis of the worm extends transversely of the slats and the worm is rotatively connected with a sprocket 21 arranged so that the chain 22 passing over the same may hang without interfering with the slats. Thus when the chain 22 is pulled in one direction or the other, the to slat 17 will be rocked on its pivots. Wlll be described hereinafter, the tilting or rocking of this top slat is communicated to the other slats of the blind for opening and closing the spaces between the same.

For the purpose of holding the slats parallel and in spaced relation when the blind is extendedand also permitting the progres sive and successive collapsing of the slats, a

: novel tape of jointed metal links may be provided, this tape being described and claimed in our application renewal Serial Num- 'ber 238,826,-filed November 19, 1919. Pref erably,'there are two pairs of metal tapes,

the other at the rear of the blind. AS. shown in Figs. 1 and 2, these tapes oom prise ,a series of rigid links 23 pivotallyv connected together at their ends. For this purpose the end' of one link is slightly offset as at 2 1 and the adjacent end of the one of each pair being at the front and devices are interposed between the thereby clamp the slat.

so that as viewed on edge they are in substantially midway of their length with apertures for pivot pins 30, these pins pivotall supporting the slat carrying devices who constitute the subject matter of this application.

Although a specific arrangement of bllnd and a specific form of tape for spacing the slats of the blind and collapsing them have been described, it isto .be distinctly understood that the slat ca rrying devices are adapted for use in connection with other formsof tapes or blind collapsing means and other arrangements of the bllnd. -As clearly shown in Fig. 2, the slat car ing ront and rear tapes'and secured to said tapes so that they are always held in substantially parallel relation.

Referring now to Figs. 3, 4 and 5, the slot bearing device or clip may be formed from a wire stock bent up to form the hook or slat edge engaging parts 31. y hook portions the wire may be formed wlth an s-shaped spring portion 32 which acts to draw the hooks 31 .toward each other to Preferably, these hook portions are formed by bending the .wire back on itself as shown and the free ends are bent to formeyes 33, one manner of bending the free ends being shown 1n Fig. 3 and another in Fig. 5, the eye being shown at 33 in the latter figure. As the hooks are formed of two thicknesses of wire, it will be seen that the have considerable not be bent out of The eyes 33 are provided for the purposeof pivotally connecting the clips to the tapes of the blind and it will be seen that the slats S may be'assembled in the blind merely'by separating the hooks 31 to permit the edges of thp blind to pass the same and then allow the spring portion 32 to pull the hooks together so that theyclamp the slat. Thus no perforations are formed in the slats and no screws or nails are required to secure the clips to the slats and consequently the cost of manufacture of the slats is limited merely thGIIIlOI'Q, this construction permits theto sawing them to the proper lengths. F urowner of the blind to replace a broken slat, the operation of removing and inserting a slat being so simple that any one can perform it. Moreover the construction of the clips is such that slight variations in the widths of the slats are permissible.

A modified form ofclip is illustrated in I Fig. 6. This clip may be pressed up from a strip of thin metal and comprises the hook portions 40 and the 'end tabs 41. Prior to forming the hooks 40 the strip is out to form the tongues 42 adapted to be be it into the Intermediate the.

' said position shown at the left of the clip of Fig. 6 so that the end of the-tongue engages on the top surface of the slat, the-apertures left by bending up the tongues forming; eyes 43 for pivotally connecting the clip to the tapes of the blind. In applying a slot to the cllp one edge of the blind is slipped under the left-hand tongue of Fig. 6 and then the opposite edge is pushed down and passes the vertical tongue 42 until the central portion 4-4 of the clip lies flat against the lower surface of the slat. Then the vertical tongue 42. is bent down against the upper surface of the slat. In this manner the clip is securely fastened to the slat and yet the slat may be removed by merely bending one of the tongues 42 up into vertical position. i 1

Although a'specific structure has been described, it is understood that changes may be made without departing from the spirlt gage the opposite edge of the slat, and an intermediate spring portion for drawing hook and part together to clamp the slat.

adapted to engage an edge of a slat, another hook adapted to engage the opposite edge of the slat, and means for pulling the hooks 1'2. As an article of manufacture, a'clip for. the slats of louvre blinds having a hook 1 0 toward each other to clamp the slat between said hooks.

3. As an article of manufacture, a clip for the slats of louvre blinds having a hook adapted to engage an edge of a slat, another hook adapted to engage the opposite edge of i the slat, and spring means for pulling the hooks toward each other to clamp the slat between said hooks.

4. As an article of manufacture, a clip for the slats of louvre blinds including hooks adapted to engage the opposite edges of the slat, each end of the clip being formed with an eye.

5. As an article-of manufacture, a clip for the slats of louvre blinds including 'end parts adapted to engage the opposite edges of a slat and an S-shaped spring portion intermediate said parts adapted to lie flat against the slat.

In testimony whereof we afiix our signatures. V
